The RNA step feeder is a compact low noise alternative to a bowl feeding system and in many circumstances components can be tooled without the aid or air.

The RNA step feeder is manufactured in such a way that the static hopper, which has a very low filling height, can be loaded manually. The components are collected from the hopper by elevating plates, pre-sorted and fed to the top without any further feeding technique until they reach the desired transfer height.

Key features of the RNA step feeder are that it operates quietly and without vibration.

Our experienced staff are available to provide advice and offer this system to you which can be adapted and integrated with multi-lane tracks to meet your requirements.

Standard Step Feeder hopper sizes range from 10 to 60 litres capacity and on request can be made to suit your individual requirements.

What is a step feeder?

Step feeders operate by raising a series of steps that create an upward waterfall effect. The component parts are transported into the rail of the singling mechanism via these steps. Vibration is used only near the rail to position the parts correctly for automatic feeding. The gentle part handling and low-friction feeding ensure minimal damage to the components, making step feeders especially suitable for industries that handle delicate products or require gentle processing.
